In critically ill adults (p), how does the daily use of chlorohexidine (I) compared to sterile water reduce VAP (ventilator-associated pneumonia) (O) during hospitalized stay (T)?
Roy's Adaptation Model (RAM) states that the "nursing process is a problem solving approach for gathering data, identifying the capacities and needs of the human adaptive system, selecting and implementing approaches for nursing care, and evaluation the outcome of care provided" ("Application of Roy's Adaptation Model," 2012). This approach seems uniquely well-suited to the question of how to reduce ventilator-associated pneumonia, a common complaint of patients during hospital stays. RAM focuses on objective analysis of the problem and attempting to provide solutions which address human needs through a scientific approach to care. The first step of the nursing process is gathering data, in this case determining why pneumonia is so common amongst patients. Next identifying "internal and external stimuli" that give rise to the health problem followed by a diagnosis and goal setting for improvement ("Application of Roy's Adaptation Model," 2012). After goals are set, the intervention is followed by an evaluation of the evidence to determine its efficacy. It also reflects the fact that when human beings cannot supply...
This is the approach I must take to determine if the use of chlorohexidine provides significant protections versus water in reducing ventilator-associated pneumonia. A quantitative study would be the most appropriate method, involving comparisons of an experimental and control group, one of which received the intervention, the other of which received standard treatment. Demographic characteristics in both groups would need to be balanced; in other words, they would need to be subjected to the same internal and external stimuli; both would have to have relatively equal health status to avoid extraneous variables affecting the outcomes (i.e. rate of illness).
Another potentially useful theory would by Betty Neuman's Systems Model which stresses the different factors which can affect human health. Human beings are "a system in which there is a continuous flow of input and process, output and feedback. It is a system of organized complexity, where all elements are in interaction" (Gonzalo 2011). Finding a more effective agent to prevent infection than water is an example…

Sr. Callista Roy Sister Callista Roy was named after Saint Callistus, a pope and martyr, from the Roman calendar on the day of her birth, October 14, 1939 at the Los Angeles Country General Hospital to a big family, which was deeply devoted to God and the service of others (Office of the Nurse Theorist 2002). Her mother was a nurse who lived and taught the values of faith, hope and
(Marriner-Tomey; Alligood, 2006) After proper interpretation of patient's actions and the process recordings, the nurse would be in a position to intervene a better plan of care and assistance for the patient. The plan of care would be included as individual therapy through which the nurse will help the patient directly and the familial therapy too as the nurse will also help the family members of the patient to refine
Theoretical Foundations of Nursing: Nursing can be described as a science and practice that enlarges adaptive capabilities and improves the transformation of an individual and the environment. This profession focuses on promoting health, improving the quality of life, and facilitating dying with dignity. The nursing profession has certain theoretical foundations that govern the nurses in promoting adaptation for individuals and groups. These theoretical foundations include theories, theory integration, reflection, research and
Remote Nursing Review The Roles of Registered Nursing in Shaping and Providing Care in Rural and Remote Locations: A Literature Review The roles and perspectives of nursing have undergone major changes in the past several decades, continuing the rapid and profound development that this area of medical science and art has experienced in its relatively brief history. For quite some time, nursing existed either as a highly denigrated and unskilled profession looked
Feeding intolerance has been identified as a significant problem for infants in the Neonatal Intensive Care Unit (NICU). Inquiry has revealed massage therapy as a possible nursing intervention for the problem (Shaeri et al., 2017). Additional knowledge is desired to determine if new research findings present clinically significant evidence for use of the intervention in the NICU patient population. Toward this end, a PICO question has been formulated: does massage
In 1858, Louis Pasteur identified germs, proving that diseases did not 'spontaneously' arise as nightingale thought (Atwell, 1998). However, it was Nightingale that began work as to the conditions that promoted the growth of germs, but she would not know this for many years. The Crimean War: Putting Theory Into Practice When the Crimean War broke out, she began work at once in a British hospital. Her emphasis was placed on
